.T Q all whom 'it may concern:

Be it known that l, WrLLniMl-l. Drinnen,

a citizen ol the United States, residing in the city ofv Syracuse, county of nondaga, and State of New York, have invented certain new and useful. Improvements in Apparatus for Forming Bilged Barrel-Bodies of Papen Pulp of-Wliieh the following is a description. yinvention relates to the form of appa ratos for this purpose described in an application for Letters Patent heretofore filed by me, Serial No. 355,844, and its Vobject is, while retaining the general principles of construction and operation. of said apparatus, to elect certain improvements in de tails of construction, and obtain `increased efficiency. To this end, in inyrpresent construction, l inter ose between the bilged forming roll and t. e transfer' roll an auxil iary, or carrying Jroll, of the same `size andv shape asvthe forming rolhand'loeated above the forming roll, and also above, 'or partly above, the sectional transfer' roll.` With this arrangement the `web of pulp (having beenv suciently strengthened for the purpose .by the application of a suitable degree of suetion thereto), is'lifted by hand frein the forming cylinder, when it reaches the proper `point thereon, and `placed upon. the auxiliary roll, around which it is carried until, vhen it reaches the horizontal diameter of tins roll onthe sideopposite to its point of application, it separates from the roll and is deliv ered by gravityto the section al transfer' roll, is carried toandV deposited upon thernandrel. l y s ln order to taire up the slaclrof the web as it `passesfroin the forming roll to the auxiliary roll and avoid the formation of folds or ridges in the web, l internose between these rolls a graduated air blast having a bow-shaped aperture conforming to the bilgreA of the web, so that the web is held in itl itsbilged shape as it passes to the auxiliary f roll and is laid smoothly thereon. A similar air blast may be interposed between the aux-- iliary roll and the transfer roll to take up 'any excess ol slack at this point and enable the web to he laid smoothly upon the transfer roll.' By those nieans the web of pulp is carried through the apparatus and laid upon the transfer roll, and Vtheme transferred to the niandicl and Wound thereon, without.

straining or wrinh'linpl in any part thereof.

The invention 'will be `best understood by reference to the accompanynig drawings, of Which-- Figure l is an end view, lig. 2 is a planA view, and Fig. 3 is .a transverse sectional view ol.' the apparatus. y

Referring to the udrawings, A., indicates a pulp containing tank, adjoining which isa waste tanlr or save all, A',

B is the bilge shaped forming to `revolve within the tanlr` A, and havingl a erforated, wire covered shell; C, is a suction or; located within the roll, B, and mounted by rneans of hollow arms, g, upon a hollow shaft, G, which is connected with an air eze haust apparatus of any usual or suitable con struction, not shown in the drawings. ln

\ operation the suction box, C, is set so as to be partly below and partly above the surface of the pul in the tank, A. It may be adjusted circuinlerentially of the roll, B, byrotating the shaft, (l, by means of the arno, J), and threaded rod, b, and its pressure against the interior of the roll, B, may he adjusted by means oi' set-screws, u., e.

D, is the metal, s1nooth-surfaeed auxiliary roll rotatablyv mounted above. the forming roll, l5. if desired, this vauxiliary roll may be heated by steam pipes, or otherwise, so to partially' dry Ikthe nioist web of pulp in` its passage over the roll.

E, is the concave surfaced transfer roll rnade up of independent, wire covered sec-` tions, rotatably mounted on a fixed shalt,'

upon and be taken up bythe transfer roll.y

The sections ol? the transfer roll are drivenby a bilge-shal'icd driverol1, F, which has the saine eine and shape as the forming' roll.
